there are basically two types of UPS' around: online and stand-by or fly-by.

The online version is much more expensive but also much better in critical conditions.

You have the choice between four individual boxes or one big box.

Cases like this let the online version shine. Stand-by versions fail pretty often especially if you have a neighbour around running big engines powered directly from the power lines.

Even big air-cons can cause the problems.

Linux} computer? Is there a UPS that is designed for heavy use and a very short (5- to 10-second) uptime? I'll need one that can

I do not think that it is a good advice to go for 10 second uptime. Take a rating fitting your machines (400W power rating for the machine, 600VA for the UPS) with at least 10 minutes uptime.

APC supplies you with both types of UPS.

All APC I have seen failing were of the fly-by type, all other were the online version. I think, it will be the same for any other brand.

But do not drop dead when you see the price difference. This will be money well spend.
